SPECIFICATION forming part of Letters Patent No. 574,345, dated December29, 1896.

' Application filed April 16', 1896. Serial No. 587,813. on. model.)

T0 at whom it may concern:

Be it known that we, NELSON D. STANLEY and JOHN S. REYNOLDs,citizens ofthe United States, residing at Essex Junction, in the county ofChittenden and State of Vermont, have invented certain new and usefullinprovements in Trolleys, of which the followingis a full,- clear, andexact description, reference being had to the accompanying drawing,forming a part thereof, and in which the figure is a side elevation of atrolley with our improvements applied, the upper end only of the polebeing shown. v

Our invention relates to that class of trolleys-in which an auxiliarytrolley-wheel is (or wheels are) employed.

The object of the invention is to provide an auxiliary trolley-wheelwhich may be brought into line with the main wheel by means of the ropeby which the trolley-pole is operated. A further object is to provide asimple and effective means by which the auxiliary trolley may freelymove up and down and also laterally and yet be controlled by thetrolleyrope; also, to provide a simple spring mechanism for throwing theauxiliary trolley up to the line-wire.

The invention will first be described, and then specifically pointed outin the claims.

Referring to the drawing, A represents the upperend of a trolley-pole,which is provided With a fork A, within which the main trolleywheel B isjournaled by means of the spindle B. From this spindle Bis freelysuspended a yoke C, from the lower end of which extends rod 0, providedwith a shoulder 0 and encircled by a spiral spring 0 The rod 0 isinclined or curved and extends at its upper end through an aperture toin the trolley-pole just at the base of its fork. The spring 0 bears onthe shoulder C and on the trolley-pole at the inner end of the aperturea and tends to press the yoke O upwardly.

D is an arm pivoted between its ends by a bolt d to the bottom of theyoke C, so as to be swung upwardly by the yoke and yet have ahorizontally-turning movement thereon. The outer or upper end of the armD is curved upwardly and forked to receive the auxiliary reartrolley-wheel E, while the opposite end of arm D extends forwardlybeneath the trol ley-pole, where it is curved or inclined downwardly andprovided with an aperture D.

A is an eye secured to the under side of the trolley-pole just inadvance of the aperture D, and to which eye is pivotally connected theeyefon the upper end of a link F,- which extends down through theaperture D. The trolley-rope G is secured to an eye on the lower end ofsaid link.

H- is a line-wire, and both wheels B E are shown engaged therewith.Should the main wheel B be forced away from the wire, the currentthrough the trolley will not be broken, as spring 0 will press yoke Oupwardly and hold the auxiliary wheel E to the wire. In passing around acurve the auxiliary trolleywheel will readily follow the curve, as itsarm D will then swing horizontally on its pivot or bolt d. hen adownpull is exerted on rope G, the link F will draw or force the rearend of arm D inward directly under the pole A, which will bring thewheel E in line with the main or front wheel B.

Our invent-ion has reference not only to the continuity of the flow ofthe current, but it also provides a simple and efifective means forcollecting any amount of current that may be required. It has beenproven that one wheel will not collect a sufficient current to propelthe extra large motors now being brought into use; but by this inventionone or more than one auxiliary wheel may be used, as occasion mayrequire.

WVhile our invention may be applied to a collector carried by the car inany convenient manner, yet we prefer the form of, our device in whichthe trolley-wheels are carried above the car.

We do not restrict ourselves to the exact construction and arrangementshown, as it is apparent that changes may be made Without departing fromthe spirit of our invention. If desired, the spiral spring may bereplaced by any other spring that will accomplish the same result.

"What we claim is- 1. The combination with the trolley-pole and mainwheel, of avertically-swinging yoke depending from the spindle or axisof said wheel, an arm secured to the lower end of the yoke and having anauxiliary or rear trolleywheel, and a spring pressing the yokerearwardly and upwardly to hold its wheel to the wire, substantially asdescribed.

2. The combination with the trolley-pole having a fork in which ismounted the main wheel; said pole having an aperture through it at thebase of the fork, of avertically-swingin g yoke depending from the axisof said main wheel and having a rod extending upwardly through theaperture in which it slides, a spiral spring on the rod, and bearingagainst the pole and a shoulder on the rod to press the yoke rearwardlyand upwardly, an arm projecting rearwardly and upwardly from the bottomof the yoke and the auxiliary trolleywheel carried by said arm,substantially as described.

3. The combination with the trolley-pole and the main wheel, of aVertically and transversely movable arm mounted beneath said wheel andextending in front and rear thereof,

an auxiliary trolley-wheel carried by the rear upper end of said arm, alink pivoted to the pole and in sliding connection with the lower orforward end of said movable arm and adapted at its lower end to beconnected to the trolley-rope, and a spring for holding the auxiliarywheel up to the wire, substantially as described.

t. The combination with the trolley-pole and its main wheel, of avertically-swinging spring-pressed yoke depending from the upper end ofthe pole, an arm pivoted between its ends to the lower end of the yoketo be swung upwardly therewith and also to swing laterally thereon, anauxiliary wheel mounted 011 the rear upper end of the arm, and afreelyswinging link depen din gfrom the trolley-pole and passing throughan aperture in the forward end of said pivoted arm; the lower end of thelink being adapted for connection with the trolley-rope, substantiallyas described.

5. The combination with the forked trolleypole and the maintrolley-wheel mounted in said fork, of a vertically-swinging yokedepending freely from the wheel-spindle and having a rod extendingupwardly and forwardly through the fork and through an aperture in thepole, a spring encircling the rod and pressing it rearwardly, an armpivoted between its ends to the bottom of the yoke to be swung upwardlytherewith and laterally thereon, an auxiliary trolley-wheel mounted onthe rear upper end of the arm; an aperture formed in the lower forwardend of said arm, and a link pivotally connected with the pole andextending down through said aperture in the arm for connection with thetrolley-pole, substantially as described.

6. The combination with the trolley-pole and its main wheel, of atransversely-swingin g arm at the under side of the upper end of thepole and projecting rearwardly and upwardly beyond the pole and thereprovided with an auxiliary trolley-wheel; the lower forward end of thearm being provided with an eye, and a freely-swinging link or connectionextending from the pole down through said eye for connection with thetrolley-rope, substantiall y as described.
